Hi, I received two 4 to 8 pin adapters with my card, but eventually I just used an 8 and a 6 pin connector (On the VGA rail) from my PSU and the card seems to be working fine, except that it's overheating, but I read abit about that and I just wanna make sure It's not supposed to be connected to the PSU in a very SPECIFIC way. My PSU is a 1000W Antec.

Thanks for reading.

Never use Molex/PCI-E adaptors (2x4 pin white to single 6 or 8 pin PCI-E) on a powerful card, the Molex leads are only designed to run HDDs and other low power items, by using the 6 and 8 pin PCI-E leads directly from the PSU you have connected the card correctly.

The R9 290 is actually designed with a 95C target temperature although once it hits <>90C its Powertune BIOS routines will begin to throttle it and will cap the temperature at the 95C maximum by further reducing the cards performance as required.
If you're not using the latest BETA drivers from AMD already you should update to those because they fix some issues with the fan speed not being correctly reported/read, they don't as such lower the top temperature but do help to...

How is it overheating? The card is designed to run at 90C supposedly. You can adjust that in your Catalyst Control Suite, to a temp that you feel comfortable with, but with that you will see a drop in performance, or you can just allow the fan speed to go up to 100% if you want your PC to sound like a hair dryer =)

If you would like more detailed explanations read here: http://www.tomshardware.co.uk/radeon-r9-290-driver-fix,review-32821.html
Unless you swap the stock cooler for something better I'm afraid you'll have to live with the noise and high load temperatures. There's a useful article here on changing the cooler for something much better: http://www.tomshardware.co.uk/r9-290-accelero-xtreme-290,review-32828.html Obviously, this voids the warranty. :(
As a final point, that sort of card can produce mad frame rates in some games, try turning Vsync ON, by capping the frame rate to 60 FPS it effectively slows the card, thus reducing its workload, fan speed and temperature.
